In this study, an image-based approach is proposed to help farmers calculate rice prices more accurately. YOLOv5 is used to detect and extract the scales in the images taken from the harvesting of rice crops. Then, various image processing techniques, such as brightness balance, background removal, etc., are compiled to determine the needle position and number on the extracted scale. Lastly, geometric transformations are proposed to calculate the weight. A real dataset of 709 images is used for the experiment. The proposed method achieves good results in terms of mAP@0.5 at 0.995, mAP@[0.5:0.95] at 0.830 for scale detection, and MAE at 3.7 for weight calculation.</p> 2023-02-03T09:38:39+08:00 Copyright (c) 2023 An Cong Tran, Thanh Trinh Thi Kim, Hai Thanh Nguyen Short-Term Rainfall Prediction Using Supervised Machine Learning 2023-02-02T19:24:40+08:00 Nusrat Jahan Prottasha Anik Tahabilder Md Kowsher Md Shanon Mia Khadiza Tul Kobra <p>Floods and rain significantly impact the economy of many agricultural countries in the world. Early prediction of rain and floods can dramatically help prevent natural disaster damage. This paper presents a machine learning and data-driven method that can accurately predict short-term rainfall. Various machine learning classification algorithms have been implemented on an Australian weather dataset to train and develop an accurate and reliable model. To choose the best suitable prediction model, diverse machine learning algorithms have been applied for classification as well. Eventually, the performance of the models has been compared based on standard performance measurement metrics. The finding shows that the hist gradient boosting classifier has given the highest accuracy of 91%, with a good F1 value and receiver operating characteristic, the area under the curve score.</p> 2023-02-02T19:24:39+08:00 Copyright (c) 2023 Nusrat Jahan Prottasha, Anik Tahabilder, Md Kowsher, Md Shanon Mia, Khadiza Tul Kobra Online MEMS-Based Specific Gravity Measurement for Lead-Acid Batteries 2023-01-06T09:41:11+08:00 Yashwant Gulab Adhav Dayaram Nimba Sonawane Chetankumar Yashawant Patil <p>Traditional methods for measuring the specific gravity (SG) of lead-acid batteries are offline, time-consuming, unsafe, and complicated. This study proposes an online method for the SG measurement to estimate the state-of-charge (SoC) of lead-acid batteries. This proposed method is based on an air purge system integrating with a micro electro mechanical system sensor. Through the proposed strategy, the SoC measurement achieves up to ±1% accuracy. The technique has an SG accuracy of ±0.002% which is better than the glass hydrometer accuracy of ±0.005% in the battery charge reading. The experimental results show that the high accuracy and precise measurements of SG and SoC can be conducted by using the proposed method.</p> 2023-01-06T00:00:00+08:00 Copyright (c) 2023 Yashwant Gulab Adhav, Dayaram Nimba Sonawane, Chetankumar Yashawant Patil Maritime Computing Transportation, Environment, and Development: Trends of Data Visualization and Computational Methodologies 2022-12-30T23:47:22+08:00 Thanapong Chaichana <p>This research aims to characterize the field of maritime computing (MC) transportation, environment, and development. It is the first report to discover how MC domain configurations support management technologies. An aspect of this research is the creation of drivers of ocean-based businesses. Systematic search and meta-analysis are employed to classify and define the MC domain. MC developments were first identified in the 1990s, representing maritime development for designing sailboats, submarines, and ship hydrodynamics. The maritime environment is simulated to predict emission reductions, coastal waste particles, renewable energy, and engineer robots to observe the ocean ecosystem. Maritime transportation focuses on optimizing ship speed, maneuvering ships, and using liquefied natural gas and submarine pipelines. Data trends with machine learning can be obtained by collecting a big data of similar computational results for implementing artificial intelligence strategies. Research findings show that modeling is an essential skill set in the 21st century.</p> 2023-01-01T00:00:00+08:00 Copyright (c) 2023 Thanapong Chaichana On the Estimation of the Mission Performance Index of Unmanned Surface Vehicles Based on the Mission Coverage Area 2022-12-30T23:47:22+08:00 Jae-Yong Lee Nam-Sun Son <p>For mission planning and replanning of multiple unmanned surface vehicles (USVs), it is important to estimate each USV’s mission performance in terms of sea surveillance (e.g., illegal ship control). In this study, a mission performance index (MPI) is proposed based on the mission coverage area for estimating the USVs’ mission performance of illegal ship control. The penalty value is considered in the MPI calculation procedure owing to the track-off of the USV. In addition, the USV simulation is conducted under illegal ship control, and the MPI is calculated based on changing the mission coverage area. The results show that the MPI increases with the path width of the mission coverage area.</p> 2023-01-01T00:00:00+08:00 Copyright (c) 2023 Jae-Yong Lee, Nam-Sun Son Calculation of Temperature-Dependent Thermal Expansion Coefficient of Metal Crystals Based on Anharmonic Correlated Debye Model 2022-12-30T23:47:22+08:00 Tong Sy Tien Nguyen Thi Minh Thuy Vu Thi Kim Lien Nguyen Thi Ngoc Anh Do Ngọc Bich Le Quang Thanh <p>This study aims to calculate the anharmonic thermal expansion (TE) coefficient of metal crystals in the temperature dependence. The calculation model is derived from the anharmonic correlated Debye (ACD) model that is developed using the many-body perturbation approach and correlated Debye model based on the anharmonic effective potential. This potential has taken into account the influence on the absorbing and backscattering atoms of all their nearest neighbors in the crystal lattice. The numerical results for the crystalline zinc (Zn) and crystalline copper (Cu) are in agreement with those obtained by the other theoretical model and experiments at several temperatures. The analytical results show that the ACD model is useful and efficient in analyzing the TE of coefficient of metal crystals.</p> 2023-01-01T00:00:00+08:00 Copyright (c) 2023 Tong Sy Tien, Nguyen Thi Minh Thuy, Vu Thi Kim Lien, Nguyen Thi Ngoc Anh, Do Ngọc Bich, Le Quang Thanh
